FlightAPI Track Flights by Route

Use this endpoint when you need to discover or monitor all flights operating between two specific airports, rather than tracking a single known flight number. Ideal for route-level analysis, finding available connections, or monitoring traffic on a corridor. Prefer over the single-flight tracker when the flight number is unknown and only origin/destination are known.

• Invalid airport codes return an error response
• No flights found on the route returns empty results
• Unsupported or low-traffic routes may return limited data
• Network timeout for real-time data fetch
• Malformed route parameters return 400-level errors
